Further Details

High-Density Media Converter System II, Fiber Mode-Conversion/Repeater Modules, 155-Mbps belong to a large family of modular media converter and communications options that provide an exceptional range of choices for your managed enterprise network. The High-Density Media Converter System II is particularly well suited for network-extension applications, offering a wide range of hot-swappable converter modules for network extension over fiber. The system offers a range of modules that are not usually available with chassis-based media converter systems.

This system can adapt to even the most demanding network configurations. All converter modules are hot-swappable—you never need to power down a chassis to change a module.

The modules featured here are protocol-independent fiber mode-conversion/repeater modules that convert multimode to single-mode fiber. Use them to add extra distance—up to 80 kilometers (49.7 mi.)—to your fiber infrastructure. Or use them for migrating from a multimode fiber infrastructure to single-mode one.

Supporting up to 155 Mbps, they're typically used for Ethernet or Fast Ethernet. But because they're transparent to protocol, they can also be used in an OC-3 ATM (155-Mbps) environment.

All the modules include FiberAlert™ to notify you of "silent failures" and help you troubleshoot problems. No more time wasted searching for them! You can check a link by observing the status of the mode converter's Link LED.

The FiberAlert function informs you when a fault occurs on one fiber strand and the link can't carry bidirectional communications between two fiber devices. With FiberAlert, the link status of one end is mirrored at the opposite end. If a strand isn't available, and you have FiberAlert enabled, the receiver end device notes the loss of the link and stops transmitting data until it receives a signal or link pulse. This means that the link status can be seen at both ends through the respective Link LEDs, thus helping you to identify and isolate faults anywhere in the fiber loop. FiberAlert works even if the fiber devices are separated by great distances.
